Landed Cost Calculator

What Is Landed Cost?

Landed cost is the all-in cost of getting a product from the supplier to your shelf (or your customer), before any markup. It is the cost you should actually use for margin calculations and pricing decisions — not the invoice price, and not FOB cost. A unit that leaves the supplier at $10 might land at $12, $14, or even $18 depending on freight, duty, insurance, brokerage, inland freight, and handling. Retailers, importers, and ecommerce operators who price off the invoice price regularly overprice low-cost items and underprice high-cost ones, eroding margin in ways that never show up until the year-end gross margin review.

Cost Components

A typical landed-cost calculation includes: the supplier's unit cost (possibly in a foreign currency with an FX conversion), ocean or air freight (usually a lump sum for the whole shipment), cargo insurance (often a percentage of cargo value), import duty (tied to HS code — use the HS/HTS Tariff Lookup), US customs fees (Harbor Maintenance Fee, Merchandise Processing Fee), customs brokerage entry fees, inland freight from port to your warehouse, handling and drayage, packaging or compliance rework, and financing costs (letters of credit, wire fees). Some of these apply at the shipment level; others are per-SKU.

Allocation Methods

Multi-line shipments create an allocation problem: if your ocean freight bill is a single $5,000 lump sum, how do you split it across 47 SKUs? The three common methods are by weight (fair for dense freight where weight drives the ocean rate), by volume (fair for light bulky freight — CBM-based rates), and by merchandise value (simple and common when weight and volume data aren't available). Different methods produce different per-unit landed costs; the calculator lets you toggle between all three on the same dataset so you can see the swing. Duty and insurance are always applied per-line on each line's own value, not via allocation, because that matches how customs brokers actually bill them.

Why This Matters for Integration

Most ERP and order-entry systems I've seen underinvest in landed-cost logic. The invoice price goes into the item master as unit cost, and everything downstream — margin reports, reorder quantities, financial statements — is built on a number that isn't true. The fix is to wire supplier invoices, freight bills, broker entries, and HTS duty rates together so that every inbound PO automatically updates the item master landed cost before the receipt posts. I've built this for QuickBooks, NetSuite, SAP, and AS/400 shops — and it is one of the highest-leverage integrations a growing importer can do.
